How satellites determine position through signal triangulation
Satellites determine position through signal triangulation by utilizing radio signals transmitted between satellites and receivers on the ground or in aircraft. Each satellite continuously broadcasts coded signals containing information about its location and the precise time the message was sent.
The receiver collects signals from multiple satellites, and by calculating the time delay for each signal to arrive, it can determine its distance from each satellite. This process involves the following steps:
- The receiver notes the time when a signal is received.
- It compares this time with the transmission time included in the satellite’s signal.
- The difference provides the distance from the satellite to the receiver, known as "pseudo-range."
Using data from at least four satellites, the receiver performs triangulation by solving a system of equations to pinpoint its exact position in three-dimensional space. This method underpins the role of satellites in modern navigation, enabling highly accurate positioning essential for air navigation systems.
